Heart Failure Awareness Survey in a Turkish Population: HFAS-TR.

OBJECTIVE: Heart failure is a leading cause of death and the most common diagnosis leading to hospitalization. Its awareness is lower than that of other cardiovascular diseases, both in the general population and among patients with heart failure (HF). This study aimed to establish the current level of knowledge about HF in patients with HF with reduced ejection fraction (HFrEF) and mildly reduced ejection fraction (HFmrEF) in Türkiye. METHODS: This questionnaire-based survey study is multicenter, conducted across 34 centers from December 2021 to July 2022. We performed a survey consisting of two sets of questions focusing on individual characteristics of the patients and HF-related knowledge. RESULTS: The study included a total of 2,307 outpatient HF patients, comprising 70.5% males and 29.5% females with a mean age of 64.58 ± 13 (56-74) years and a mean body mass index value of 32.5 ± 10 kg/m2. HFrEF and HFmrEF were determined in 74.7% and 25.3% of patients, respectively. Thirty percent of the patients were unaware that they had HF. While 28.7% of the patients thought that they had sufficient information about HF, 71.3% believed they lacked adequate knowledge. In the study, 25.2% of the participants identified dyspnea, 22% identified tiredness, and 25.4% identified leg edema as the most common symptoms of HF. Only 27.4% of patients recognized all three typical symptoms of HF. CONCLUSION: We found that the study population's knowledge about HF symptoms and the nature of the disease was poor. Educational and awareness activities are necessary to optimize outcomes and benefits.

Prediction of New-Onset Atrial Fibrillation in Transcatheter Aortic Valve Implantation.

Background: This study investigates the association between prolonged total atrial conduction time and the development of new-onset atrial fibrillation (AF) following transcatheter aortic valve implantation (TAVI). Methods: We enrolled 307 patients who underwent TAVI. Total atrial conduction time was calculated as the time between the onset of the P wave on the electrocardiography and the peak of the a' wave velocity (PA-TDI duration) on tissue Doppler imaging echocardiography. Results: A total of 263 patients were analyzed after excluding 44 with pre-existing AF. Of these 263 patients, 47 (17.8%) experienced new-onset AF after the TAVI procedure. The new-onset AF group had an older median age (80.6 vs. 77.5 years) and a higher incidence of paravalvular aortic regurgitation than those without AF (none 29.8%, mild 46.8%, moderate 23.4%). The new-onset AF group had increased end-systolic diameter (35.0 vs. 31.7 mm, p = 0.03), left atrial diameter (44.7 vs. 41.9 mm, p = 0.049), and PA-TDI duration (137.0 vs. 125.4 ms, p = 0.009). Older age, the presence of paravalvular aortic regurgitation, and prolonged PA-TDI duration were independently associated with new-onset AF in multivariate analysis. The optimal cut-off value for PA-TDI duration was 123.5 ms. Conclusions: AF in patients treated with TAVI may pose significant risks for morbidity and mortality. PA-TDI duration, a readily available echocardiographic parameter, can detect patients with a high risk of new-onset AF.

Advancements in risk stratification and management strategies in primary cardiovascular prevention.

Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality worldwide, highlighting the urgent need for advancements in risk assessment and management strategies. Although significant progress has been made recently, identifying and managing apparently healthy individuals at a higher risk of developing atherosclerosis and those with subclinical atherosclerosis still poses significant challenges. Traditional risk assessment tools have limitations in accurately predicting future events and fail to encompass the complexity of the atherosclerosis trajectory. In this review, we describe novel approaches in biomarkers, genetics, advanced imaging techniques, and artificial intelligence that have emerged to address this gap. Moreover, polygenic risk scores and imaging modalities such as coronary artery calcium scoring, and coronary computed tomography angiography offer promising avenues for enhancing primary cardiovascular risk stratification and personalised intervention strategies. On the other hand, interventions aiming against atherosclerosis development or promoting plaque regression have gained attention in primary ASCVD prevention. Therefore, the potential role of drugs like statins, ezetimibe, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, omega-3 fatty acids, antihypertensive agents, as well as glucose-lowering and anti-inflammatory drugs are also discussed. Since findings regarding the efficacy of these interventions vary, further research is still required to elucidate their mechanisms of action, optimize treatment regimens, and determine their long-term effects on ASCVD outcomes. In conclusion, advancements in strategies addressing atherosclerosis prevention and plaque regression present promising avenues for enhancing primary ASCVD prevention through personalised approaches tailored to individual risk profiles. Nevertheless, ongoing research efforts are imperative to refine these strategies further and maximise their effectiveness in safeguarding cardiovascular health.

Effects of a medium cut-off dialyzer on inflammation and cardiac and vascular function in hemodialysis patients with heart failure.

INTRODUCTION: Expanded hemodialysis (HDx) could provide clearance of larger middle-molecule uremic toxins. We compared the effect of hemodialysis with medium cut-off membranes and high-flux (HFHD) membranes regarding changes in inflammation and vascular and left ventricular function. METHODS: This was a single-center, prospective, parallel-group comparative study. Patients were divided into two groups (HDx: 25 patients and HFHD: 26 patients). All measurements were performed at baseline and 12 weeks. Serum c-reactive protein, interkelukin-18, pentraxin-3, ß-2 microglobulin, and brain natriuretic peptide were measured. We used pulse wave velocity and augmentation index to assess arterial stiffness and echocardiography to evaluate left and right ventricular function. FINDINGS: We enrolled 51 patients. Although serum c-reactive protein, interkelukin-18, pentraxin 3, and ß-2 microglobulin were significantly decreased in the HDx group (p = 0.02, p < 0.001, p = 0.002, and p = 0.02, respectively), there was no significant change in HFHD group at 12th week. Serum c-reactive protein and interkelukin-18were significantly lower in the HDx group compared to the HFHD group in the 12th week (p = 0.007 and p = 0.03, respectively). We observed a significant decrease in pulse wave velocity in the HDx group at the end of the study (p = 0.03). Although there was no significant change in pulse wave velocity in the HFHD group, pulse wave velocity was similar between the HDx and HFHD groups in the 12th week. We detected a significant decrease in the mean isovolumetric relaxation time in the HDx group (p = 0.006). However, there was no significant difference in isovolumetric relaxation time between the HDx and HFHD groups in the 12th week. DISCUSSION: HDx provides better clearance of middle molecular uremic toxins and inflammatory biomarkers, and it may be associated with better central hemodynamic parameters and diastolic functions.

Reliability and validity of the Turkish version of the Self-care of Hypertension Inventory Version 3.0 in adults with hypertension.

BACKGROUND: Hypertension is an important cardiovascular disease risk factor. Blood pressure control for hypertensive patients is crucial to prevent hypertension related complications. Ensuring and assessing self-care of hypertensive patients is important for blood pressure control and hypertension management. The Self-care of Hypertension Inventory (SC-HI) is an inventory developed for assessing self-care of hypertensive individuals. SC-HI has three subscales; maintenance, monitoring and management. OBJECTIVE: The aim of this study was to conduct Turkish version of SC-HI Version 3.0 (SC-HI V3.0) and assessing its psychometric properties for adults with hypertension. METHODS: We included 120 hypertensive patients in this methodological study. SC-HI V3.0 translated Turkish and tested for reliability and validity. To analyse structural validity item-total correlations and factor analyses was used. Intraclass correlation coefficient (ICC) method was selected for analysing scale's consistency and convergent validity was conducted. RESULTS: The mean age of participants were 54.74 ± 7.19 years and the mean duration from hypertension diagnosis were 38.19 ± 19.42 months. Translated Turkish version's factor loadings were ranged between 0.419 and 0.841. Cronbach's alpha coefficient values were 0.661, 0.880, 0.805 and ICC values were 1.0, 0.99, 0.99 for maintenance, monitoring and management, respectively. Convergent validity's correlation coefficients weak to very strong and statistically significant. CONCLUSIONS: Turkish version of the SC-HI Version 3.0 is reliable, valid and useful scale for assessing self-management in hypertensive adults for clinical practice and research purposes.

A Challenging Case of Viral Pneumonia in the COVID-19 Pandemic Era.

Cytomegalovirus (CMV) is a DNA virus that can cause widespread, severe infection in immunocompromised patients. While CMV usually leads to a subclinical infection in immunocompetent individuals, it can rarely cause severe disease in this population. The SARS-CoV-2 virus is an RNA virus and part of the Coronaviridae family. SARS-CoV-2 led to the COVID-19 (coronavirus disease 2019) pandemic. Even though COVID-19 usually presents with signs and symptoms of upper respiratory tract infection in younger adults, viral pneumonia, cytopenia, and neurological symptoms become more apparent with increasing age. Herein, we describe an immunocompetent 73-year-old female patient in whom oxygen demand and pancytopenia developed during hospitalization for post-ablation inguinal access site infection. The thorax CT revealed viral pneumonia, but two subsequent SARS-CoV-2 polymerase chain reaction (PCR) tests and a viral respiratory multiplex PCR panel were negative. The CMV viral load was high in the blood sample, and the patient responded to valganciclovir treatment. Although SARS-CoV-2 should be evaluated in patients with viral pneumonia and cytopenia, other viral etiologies mimicking SARS-CoV-2 infection, such as CMV, should not be overlooked in the era of the COVID-19 pandemic.

Electrocardiogram Features in Non-Cardiac Diseases: From Mechanisms to Practical Aspects.

Despite the noteworthy advancements and the introduction of new technologies in diagnostic tools for cardiovascular disorders, the electrocardiogram (ECG) remains a reliable, easily accessible, and affordable tool to use. In addition to its crucial role in cardiac emergencies, ECG can be considered a very useful ancillary tool for the diagnosis of many non-cardiac diseases as well. In this narrative review, we aimed to explore the potential contributions of ECG for the diagnosis of non-cardiac diseases such as stroke, migraine, pancreatitis, Kounis syndrome, hypothermia, esophageal disorders, pulmonary embolism, pulmonary diseases, electrolyte disturbances, anemia, coronavirus disease 2019, different intoxications and pregnancy.

Percutaneous interventions of coronary artery fistulas: a single-center experience.

Introduction: Coronary artery fistula (CAF) is a congenital communication between the coronary artery and other vascular structures or cardiac chambers. Percutaneous CAF closure is an emerging alternative to surgery, but long-term outcome data are limited. Aim: To review our center's experience with percutaneous CAF closure methods. Material and methods: Patients who were admitted to our department and underwent percutaneous coronary artery fistula intervention between January 2002 and April 2022 due to presence of CAF-related symptoms or complications were retrospectively analyzed. Data were obtained retrospectively from the hospital electronic database. Results: A total of 39 patient were included. Mean age was 57.3 ±12.5 years and 23 (59%) patients were male. The most common symptom was angina (69.2%) and 51.2% of the patients were under treatment with at least one anti-anginal agent at admission. The right coronary artery (n = 19) and left anterior descending artery (n = 19) were the most common sites of CAF origin, and the pulmonary artery (n = 22) was the main drainage site. Coil embolization was performed most frequently and occlusion via cyanoacrylate in 3 patients and detachable balloon angioplasty in 1 patient were preferred. Percutaneous occlusion was achieved in 34 cases, 2 of the 5 failed cases underwent surgical occlusion, and remaining patients were treated with anti-anginal drugs. Complications occurred in 6 (15.3%) patients and all of the patients recovered without sequelae. Conclusions: Coronary artery fistulas may present with different symptoms or complications and there are several techniques for percutaneous occlusion. Percutaneous closure of CAF is feasible and safe in anatomically suitable vessels, with good results at follow-up.
